COMBINED CLEVIS AND LAPLIN K.

Specification of Letters Patent.

Application filed October 4, 1915. Serial No. 54,048.

To all whom it may concern Be it known that I, EUGENE TIMMERMAN, a citizen of the United States of r'tmerica, residing at Ward, in the county of Saluda and State of South Carolina, have invented certain new and useful Improvements in Combined Clevises and Laplinks, of which the following is a specification.

This invention relates to a combined clevis and laplink for plows, cultivators, and the like, and the object is to provide a. novel clevis which may be readily applied to a plow beam whereby the front end of the plow beam may be adjusted vertically for the purpose of gaging the depth of the furrow.

The principal object of my invention is to provide a simple and efficient device in which the attaching laplink hook may be readily adjusted in difierent vertical positions, whereby the required adjustment of the plow may be effected in a simple and convenient manner without the use of tools.

A further object of my invention is to provide a combined clevis and laplinl-z of this character which is strong, durable, and inexpensive in construction, and which can be readily substituted for the ordinary clevis.

With these and other objects in view, the invention consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and pointed out in the claims.

In the drawings: Figure 1 is a side elevation of the forward end of a plow beam with my invention attached thereto, showing the laplink in one position. Fig. 2 is a vertical sectional view of a plow beam with my invention in elevation showing the laplink in another position. Fig. 3 is a perspective view of my invention detached from the plow beam.

The reference numeral 1 designates the forward end of a plow beam to which is secured my clevis 2 having arms 3 which are adapted to lie adjacent the upper and lower sides of the beam and are formed integral with the spacing bar 10.

The clevis is secured to the beam by means of a bolt 4 provided with a screw threaded end which passes through apertures 5 and 6 in the arms 3 of the clevis and through a vertical opening 7 in the beam. The screw threaded end of the bolt l. is designed to mesh with the threads of the aperture 5 of the lower arm of the clevis, whereby the clevis is held in position on the plow beam. In the forward end of the plow beam is a socket 8 which is adapted to receive an inwardly projecting stud 9 formed in the intions as a means for preventing the clevis from moving side-wise on the beam when the plow is being turned. I

The arms 3 are extended longitudinally beyond the cross bar 10 to form members 14 which are bent upon themselves to form closed eyes 11, in vertical alinement with each other. 7

12 is an arm extending forwardly from the cross bar 10 and bent upon itself to form an open eye 18, which is provided with an upwardly pro ecting guard or stop 15, said open eye being intermediate the eyes 11 and in alinement therewith.

A vertically reciprocal rod 16 is revolubly positioned in the eyes 11 and 13 and is provided with heads 17 which serve to limit its vertical movement therein. An open laplink 18 formed on the arm 19 is carried by the rod 16 intermediate its ends and extends forwardly of the same.

As shown in Fig. l, the clevis is in a normal position and the furrow made by the plow is of medium depth as required for ordinary farming. However, in the event that a deeper furrow is required the arm 19 is lifted to contact with the upper member 14 and then swung around back of the guard 15 of the open eye 18, whereupon it drops to the lower position as shown in Fig. 2, and is then swung in longitudinal alinement with the plow beam.

Thus, it will be seen, that the open laplink may be readily adjusted in different vertical positions and the required adjustment of the plow may be effected in a simple manner without the use of tools. It is obvious that any number of open eyes 13 may be positioned between the eyes 11 so that the plow may be adjusted in many different vertical positions.

What I claim is:

1. A clevis having closed forwardly projecting eyes in vertical alinement, an open eye intermediate the closed eyes and in vertical alinement therewith, a rod reciprocally Patented Uet. St, 19th.

ner side of the spacing bar 10, which func and revolubly mounted in said eyes, and means carried by said rod adapted to engage the open eye to hold the said rod in a vertically adjusted position.

2. A clevis having; closed forwardly projecting' eyes in vertical alinement, an open eye intermediate the closed eyes and in ver tical alinement therewith, a rod reciprocally and revolubly mounted in said eyes, means carried by said rod adapted to engage the open eye to hold the said rod in a vertically adjusted position, and means carried by said open eye to limit the 'revoluble movement of said rod. I v

3. A clevis having closed forwardly projectino; eyes in vertical alinement, an open eye intermediate the closed eyes and in vertical alinement therewith, a rod reciprocally and revolubly mounted in said eyes, and means carried by said rod adapted to engage the open eye to hold the said rod in a vertically adjusted position, and an upwardly disposed guard carried by said open eye to limit the revoluble movement of said rod. 7

4. A clevis comprising a spacing bar havmg rearwardly projecting arms adapted to be secured to a plow beam, members extending forwardly. and longitudinally of said arms-formed with closed eyes, an open eye extending forwardly of said spacing bar and in Vertical alinement with said closed eyes, a rod revolubly and reciprocally mounted in said eyes, a laplink carried by said rod, and means carried by said rod to hold the same in a vertically adjusted position.

5. A cleris comprising a spacing bar havi119; rearwardly projecting arms adapted to be secured to a plow beam, a stud extending rearwardly of said spacing bar and adapted to enter a recess in the end of said plow beam, members extending forwardly and longitudinally of Said arms formed with closed eyes, an open eye extending forwardly of said spacing bar and in vertical alinement with said closed eyes, a rod revolubly and reciprocally mounted in said eyes, a laplink carried by said rod, and means carried by said rod to hold the same in a vertically adjusted position.

6. A clevis comprising a spacing bar having rearwardly projecting arms adapted to be secured to a plow beam, members extendin; forwardly and longitudinally of said arms formed with closed eyes, an open eye extending forwardly of Said spacing bar and in vertical alinement with said closed eyes, a rod revolubly and reciprocally mounted in said eyes, an arm extending forwardly from said rod at right angles thereto and terminatingin a. laplink, said arm being adapted to contact with the open eye to hold it in an adjusted position.

In testimony whereof I aiiix my signature in the presence of two witnesses.
